$BTC
market capitalization as a percentage of the total cryptocurrency market cap, indicating BTC's relative strength against altcoins.
Definition
It is calculated as (Bitcoin market cap ÷ Total crypto market cap) × 100, often tracked on platforms like TradingView, CoinMarketCap, or Binance charts. Rising dominance signals capital flowing into BTC, typically during uncertainty or bear markets, while falling levels suggest "altseason" with interest shifting to other coins.
Trading Applications
Monitor BTCD alongside BTC price for signals: rising dominance + rising BTC price indicates a BTC bull run—favor BTC positions. Falling dominance + rising BTC price points to altcoin strength—rotate into alts like ETH or others. Use thresholds like 54% (altcoin entry) or 65% (BTC safety) for timing, but combine with volume and RSI to manage risk and avoid false signals.
